Lugt, D. (author)The Ems estuary suffers from high concentrations of suspended sediment, which is harmful for the life in the river. Sediment import occurs because of tidal asymmetry, a difference between the velocity of the current during high tide and low tide. The use of retention basins are a possible measure to reduce the tidal asymmetry. An analytic model,...bachelor thesis 2012

Toxopeus, S.L. (author)In the SIMMAN 2008 workshop, the capability of CFD tools to predict the flow around manoeuvring ships has been investigated. It was decided to continue this effort but to extend the work to the flow around ships in shallow water. In this paper, CFD calculations for the KLVCC2 are presented. The aim of the study is to verify and validate the...conference paper 2011

Bergsma, E.W.J. (author), Bogaard, T. (author)The general flow pattern of an open channel flow, downstream of a width restriction by two artificial dams, is analysed. A physical Froude-scaled model, under hydraulic rough conditions, with a significant large Reynolds number is used to ensure turbulent flow. Upstream of the dams the flow is uniform in transverse direction, in between and...student report 2011

Kleptsova, O. (author), Stelling, G.S. (author), Pietrzak, J.D. (author)In this paper, we focus on a conservative momentum advection discretisation in the presence of zlayers. While in the 2Dcase conservation ofmomentum is achieved automatically for an Eulerian advection scheme, special attention is required in the multi-layer case. We show here that an artificial vertical structure of the flow can be introduced...journal article 2010

Chernetsky, A.S. (author), Schuttelaars, H.M. (author), Talke, S.A. (author)Over decades and centuries, the mean depth of estuaries changes due to sea-level rise, land subsidence, infilling, and dredging projects. These processes produce changes in relative roughness (friction) and mixing, resulting in fundamental changes in the characteristics of the horizontal (velocity) and vertical tides (sea surface elevation) and...journal article 2010

Badri, M.A. (author), Wilders, P. (author), Azimian, A.R. (author)Hydrodynamic simulations of tidal currents in the Persian Gulf are presented. Water surface level and velocity have been determined by a Kelvin wave expansion as a new hydrodynamic calibration tool for estimating the dynamical field and flow patterns. In the procedure, leading to the Kelvin wave expansion, data of tidal constituents from co...report 2010

Verhagen, H.J. (author), Mertens, M. (author)In the Rock Manual [2007] two sets of equations for the determination of rock stability in breakwaters armour layers are presented. One set is the original formula presented by Van der Meer [1988], valid for deep water conditions. This set uses the parameters Hs and Tm. The other set is an adaptation of these formulae, using the parameters H2%...conference paper 2009

Kai, C. (author)Coastal zones which are known as the interface between continents and oceans are vital and important to human beings because a majority of the world's population live in such zones (Nelson, 2007). Coastal systems are among the most dynamic and energetic environments on earth and they are continuously changing because of the dynamic interaction...report 2009

Ebbens, R.E. (author)This thesis is about the stability of toe material for rubble mound breakwaters in depth limited conditions. The present equation, Van der Meer 1998, gives results for depth limited conditions but is not validated. The empirical equation is based on physical model tests done by Gerding 1993. The Van der Meer equation implies deep water and...master thesis 2009

Verhagen, H.J. (author), Van Vledder, G.P. (author), Eslami Arab, S. (author)Modern design formula for coastal structures (like rock stability formula and overtopping formula use wave parameters (H2% and Tm-1,0) which are not readily available from standard boundary condition wave data. For transforming values like Hs and Tp to the parameters used in the new formulas, often-fixed conversion factors are used. However,...conference paper 2008

Gejadze, I.Y. (author), Monnier, J. (author)In the context of river hydraulics, we develop the idea of a richer local zoom model superposed to a given global model. The local zoom model (2D shallow water equations in flooded parts) describes additional physical phenomena which are not represented by the basic global model (1D shallow-water equations with storage area). The weak coupling...conference paper 2006

Djadel, K. (author), Ern, A. (author), Piperno, S. (author)Shallow-Water Equations are encountered in many applications related to hydraulics, flood propagation or dam break problems. This set of nonlinear hyperbolic equations models a fluid flow in a domain where the depth of the fluid is much lower than its horizontal dimensions. Usually, these equations are treated using Finite Difference, Finite...conference paper 2006

Verhagen, H.J. (author), Reedijk, B. (author), Muttray, M. (author)Experience has shown that stability parameters for breakwater armour are different for steep and shallow foreshores, as well as for deep and shallow water. A change from a deep water spectral information (Tm0) to shallow water spectral information (Tm-1,0) does not completely explains this difference. Tests have shown that stability also depends...conference paper 2006

Bijvelds, M.D.J.P. (author)In this report the implementation and testing of a numerical model that is based on a Cartesian fixed grid in vertical direction is described. The model uses the shallow-water equations and accounts for effects of stratification. In stratified environments, the terrain-following 0-transformation, which is often used in shallow-watermodels, is...report 1998
